Closer to Cambodia than Vietnam (Cambodia actually claims it belongs to them), this is by far the largest island in Vietnam and increasingly a popular destination for foreign tourists, especially ones looking for beach resorts. Compared to islands in Thailand, I don't think Phú Quốc has much to offer but I enjoyed my time there. I was surprised how many Vietnamese people live there and how busy the town is.
Sights & Activities
Phu Quoc Airport
Since the new international airport was opened in 2012, it seems they've just abandoned the old one and left it as it is. There is a make-shift turning from the main road on to the runway where some fencing has been taken down. I don't think it's officially open to the public but people use it as a shortcut. It's mostly deserted though, so I was able to ride up and down uninterrupted.
